I received from our client a dwg file. i follow the steps in creating a topo surface file from a dwg within revit. However, revt include also the zero Z-elevation points within the file. And so it igave me a very weird result of the toposurface.
Know any good procedure in preparing a dwg file before importing/linking to revit or rather excluding all zero Z-elevation points.
For some reason I cannot generate a topo surface using the attached autocad file.
The levels are on a layer called LEVELS. The points next to the levels are on layer "0".
Some of the levels are negative ... ie: below sea level.
No topo surface gets generated and no error message appears.
I am trying to create a mass surface that is being cut by a topo plane. What I am trying to achieve or show is a height setback set from the existing topo to a height of 35'. I've tried to cutting or joining the two geometries but this will not work. There is no way to snap t the intersection of were the mass and the Topo surface meet. Is there a way to change a Topo surface into a mass? Any other way to achive this instead of massing and topo surfaces?

I promoted the existing surface shortcut into my drawing, then created a cropped surface to be put in a new drawing. After creating the cropped surface the new file shows that a surface has been created, however, the surface contains no data. I am using c3d 2012.

View 3 Replies View RelatedWhen I select all of my building pads and topo and move them vertically up or down by the SAME amount, the cut and fill volumes change. Apparently the cut/fill is being calculated relative to something that is NOT THE GRADED SURFACE. Maybe the Level line? I don't know. The volumes shouldn't change at all when I move both the topo and pads together! How can I trust these numbers?

know of a way to modify both Contour Lines (Topo) and the actual building in the same file?
i.e. without linking the file "topo" to the file "building"?
Is there any way to change the referenced surface on a Surface Elevation Label. I can see the surface in the properties but cannot change it.

I used the Volume dashboard to cal volume so when I view the surface in object viewer or 3D I see my TIN volumes surface at zero elevation is this right? I think the reason is because they want us to see both surface so they are not on top of one to another.

View 9 Replies View RelatedI have a drawing that someone else created that has a spot elevation label for a surface. It labels the surface (PAD) then automatically subtracts a set distance for another elevation (GFE) and adds a set distance for another elevation (FFE). After doing some research, it looks like it was created with an expression?
I have two questions:
First, where to go to get a better understadning of this? I'm not familiar with expressions.
Second, where can I find the expression in drawing to make an edit to the set distances. I can remove the GFE/FFE as they are separate components in the label style, but I don't see where to modify the distance it adds or subtracts.
I have created a surface, when I hover over a contour on it I used to get name,style, layer, elevation. Now I get them all except elevation, I didn't change anything (not on purpose at least) in my drawings.
View 6 Replies View RelatedI've tried to create a surface analysis by using a point group reading xdata to set the elevations and when I set my surface properties to display the elevation shades it will only allow me to set the range to 5 or less. All of the other analysis settings for direction, slope, and slope arrows allow me to input the nuber of ranges I want, but I need the elevation analysis.
View 5 Replies View RelatedIn the previous C3D 2012 version I was able to set surface transparency just setting it on a layer with defined transparency. Example: I set my "existing ground" surface to a created "EG" layer (example name) and set transparency layer to 50% (example, again) and it WORKS! My surface become transparent...
But now, in the C3D 2013, I can't get the same results... my surface is not getting transparent. I already tried to turn off/on hardware acceleration and adaptive degradation and show/hide transparency.
More details: I can get transparency on points, triangles, contours etc... but not on elevation, and this is my priority.

We work with Hydro graphic surveys that have large numbers of points. We would like to be able to display girded spot heights colored to represent the elevation. (Similar to elevation banding)
I have created a surface and then created surface elevation points on a grid with spacing of 15m. I have tried looking at setting up a style that will adjust the color depending on the elevation ie 0 to -1 = red but haven't made any progress.
I have a question about pipeline networks.
I have a civil3d pipe network that has modeled by my co-worker before.
Now I want to put that pipe network on new surface and get rim elevation from surface automatically and also after stretch it can update rim elv based on that surface.
I have a project involving 3 programs. I am creating a planned development in 3d to be 3d printed when finished. The project is a 5 acre tract containing 8 buildings. I have built the surface in C3D and each building in Revit. The buildings are not in the same Revit file. For my solid work, I will bring the files over into 3ds Max Design to section into smaller quadrants to build in the 3d printer.
The questions:
Would it be better to import the surface into Revit to merge surface and buildings together?
Would it be better to import the buildings into C3D to merge entities?
Would it be better to bring those entities into 3ds Max and then merge them into one? Will 3ds Max Design allow me to insert entities accurately in the environment?
I got this plan from a third person and, the point from the survey have the property " bloc ". In their attribute property, I can see the elevation value. but in the z of the actual bloc, it shows zero. I would like to tell C3D to use the attribute elevation for his actual Z in the drawing. How can I achieve this ?
View 6 Replies View Relatedis it possible to export elevations from a surface at a given interval? i can easily export all the data i used to build the surface, but now I am wondering if its possible to export/extract the surface to a CSV or TXT file with a position and elevations, say, every 5 feet?
View 3 Replies View RelatedI have a surface with all sorts of heights, and want to add color to different heights. Getting the color there is not that difficult, but how do I swap them around? i.e. red is 'low ground' and blue is 'high ground'. In Holland we use it the other way around though, so blue should be low ground and red high ground.
Where exactly do I change this? I've tried it in the surface style tab, surface properties tab, analysis tab, and some others, but no success so far.
I am using Civil 3d 2012 and an trying to apply elevation banding (one color) to a surface that is completely flat. Everything seems to be in order but nothing shows up. If I add another point file to it that has a variety of elevations then the elevation bands show up, if i remove it it disappears again. I can view the boundary and get elevation readings when I mouse over the surface.

I would like to sample that surface at very specific locations -- I could produce the required points in PNE format.
What I want is to find the way to: (1) import those points, (2) sample elevation from the surface at those locations, and (3) export the 3D poitns in PNEZ format.
I have been searching for a way to rotate surface spot elevation labels but have not been able to find a solution to do so. Has this feature been added to 2013 or 14? I do not want to use the point and label styles for my surface elevation, even though these can be rotated. I have several miles of roadway with many horizontal curves and would like the surface labels aligned with and along the centerline. I prefer not to update the spot elevations when the profile is revised.

Our provincial standard requires subgrade and subbase surfaces to have a normal cross slope of -3%. The base and asphalt surfaces have a normal cross slope for the driving lane of -2% and -5% for the shoulder.
I have been trying to figure out how to do this in C3D. I have thought of different ways of handling this for a straight tangent, but have not tested them. What is causing me the most grief at the moment is how to handle this in a curve with super elevation.
The transition will be different for -2%, -3% and -5% Runout distances.
Can C3D handle this? What about using Subassembly Composer?
(I should mention that I have tried with Subassembly Composer, but I am not sure how to deal with superelevation. -
I created a new surface, pasted my OG surface into it, set the build to exclude elevations less than and greater than but my surface still is showing every contour range. I want to only show contours at elevations of 371.5 and 370.5
Is it because it's a pasted surface?
xrefing a drawing that has annotated surface labels spot elevations into a Precise Grading Breakout Sheet, but making sure those labels plot screened. How do I make sure I can plot it screened?

View 4 Replies View RelatedToday I created a TIN Volume Surface. The volume surface seems to have a "resolution" issue if you will when displaying using elevation banding. In the attached screenshot note how the edges of the surface are "squared" or pixelated. Also, the blue lines are "hide" boundaries, and they have the same effect. I've created volume surfaces before with no issues until now.
The volume surface compares 2 surfaces that were created from nothing but contours. Some of the contours can be seen in the attached image.
I've tried REDRAW and REGEN, the image looks the same in model space and paper space, I've tried closing AutoCAD and reopening the file. I deleted the volume surface and then created a new one... I'm sure there's just a setting somewhere that I'm missing.
For comparison, also attached is a screenshot a "normal" volume surface that I created before. This one has no "hide" boundaries, but the edges of the surface aren't "squared."
